vIMPROVEMENT I N MACHINERY FOR -CLEANING WOOL, COTTON, &c.

i Specification forming` part of Letters Patent No. 35.621, dated J une 17, 1862.

To aZZwhom it may concern: v

Be it known that I, `STEPHEN R. PARK- lHURsT; of the city and State of New York; have invented, made, and applied to use a certain new and useful Improvement, in Means for Cleaning Gotton,Wool, and other Fibrous Substances; and I do hereby declare that the following is a full, clear, and exact description of the nature of lmy said invention, reference beinghadto `the annexed drawing. making part of this specification, wherein `I have prep! j resented a verticaleross-section of the arrangement of rollers, cylinders, andl beaters to which lmy invention relates.-

My said invention consists in the combinatiou'- of toothed feedrollers with a pair of burrcylinders and a beatenwhereby the fibers are openedand the foreign substances removed by the beater; andin combination with the said burr-cylinders I employ a third burr-cylinder and a beater that operate on the opposite sid-e of theiiber to that operated on by the first burr-cylinders, and remove any foreignsubstances that might previously'have been en-` veloped. in the fibers. From this last burrcylinder the fibers 4are taken by the licker` inV of aycarding-machine, or by a brush, doffer, or other convenient means, accordng'to requirements of the manufacturer.

In the drawing. a is the apron. A b and c are the feed-rollers, formed with surv faces of teeth set in the manner shown, so that the teeth point backward as they revolve. d' is a burreylinder formed with asurface of teeth, and the cylinder is revolved in the direction shown by the arrow with the teeth point first.'` These draw the fibers off the feedroller teeth c. p

e is aburr-oylinder. revolved in the direction shown. so that the teeth draw the fibers ofi the feed-roller band convey them toltuhe said burr- `cylinder d, the periphery of wnich, moving slightly -faster than thatof the'cylnder e, removes the fibers therefrom. All these operations open and loosen thelocks o f wool or other fibers, and the beater j', revolved in the direction shown, knocks off any burrs or foreign and they fall substances into the grate4 g,

. throwing them into the'boX k.

through the same, while any fibers are caught and returned by the cylinder e, to be operated on as before. t

From the cylinder d the fibers are'taken by the burr cylinder h, the surface of which travels faster than that of the cylinder d, and

by this the Afiber is not only opened and loos ened,'but'the side' of the Ifibrous bat that was next the-beater-cylinderj' now comes next this cylinder h, while the side of the fibrous mass that was next the cylinder d now comes'on the outside and is exposedto the cleaning operation of theseoond beater-cylinder, t', that removes any. foreign substances 'that remain,

l Y'Thus thefibers are thoroughly opened o r loosened and both sides of the mass are exposed to the cleaning operations, that effectually and thoroughly remove foreign substances, leaving the fibers ready for any, subsequent operations in the manufacturing.

lrepresents a portion-of the .licker-in of a carding machine; buta blower or any other device may be employed for' removing the e,` feedro1lers b and c, and beater f, substantially as and for the purposes specied.

2. The cylinder h and beater 'i when con,

bined with the cylinder d and beater f,where by the cotton, wool, or other ber is exposed on both sides of the bat to the operation of the beaters, as and for the purposes set forth.

AIn witness whereof I have hereunto set my signature this 26th day of March, 1862.
